Rental properties—including both short- and long-term leases—can pose special risks due to inconsistent maintenance and limited disclosure of past issues. High turnover increases the chance that leaks, spills, or infestations were overlooked or only superficially addressed. Always ask for maintenance records and inspect water-prone areas closely.

Multi-family buildings (such as condos, townhomes, and apartment complexes) carry additional concerns. Shared walls, floors, and HVAC systems can allow airborne contaminants to migrate between units. Even if one unit is well maintained, another may be a source of mold, pests, or strong odors that impact your space. For environmentally sensitive individuals, standalone homes offer greater control and isolation from external exposures.
